Abstract

The invention relates to a method and a device for producing colored glasses. The aim of the invention is to obtain a paricularly intimate mixture and to enable a quick change of the melt at the same time. To this end, the following procedure steps are applied: a melt made of a compound or fragments of glass is produced, the glass melt is further processed in at least one additional vessel, the melt is supplied to a skull device ( 3 ) (skull pot or skull channel) during subsequent processing, a dye is supplied ( 6, 6.1 ) to the melt after the melt was in the melting station ( 1 ) but before the melt enters the skull device ( 3 ) or while said melt is in the skull device.

Claims

exact text as granted — not AI-modified
1. A method for producing colored glasses, comprising: first producing in a melting-in station a melt of a glass batch or refuse glass;
 processing the glass melt in at least one further vessel; 
 supplying the melt to a skull device in the course of further processing; and 
 supplying the melt with a stain after the melting-in station and before or in the skull device. 
 
     
     
       2. A method as claimed in  claim 1 , including:
 causing two or more glass melt strands to branch off from the melting-in station; 
 at least one of the glass melt strands being provided to the skull device; and 
 supplying a stain melt to said at least one of the melt strands after the melting-in station, but before or in the respective skull device. 
 
     
     
       3. A method as claimed in  claim 1 , wherein the skull device is a skull crucible. 
     
     
       4. A method as claimed in  claim 1 , wherein the skull device is a skull groove. 
     
     
       5. A method as claimed in  claim 1 , wherein the melt is supplied with a stain before the skull device. 
     
     
       6. A method as claimed in  claim 1 , wherein the melt is supplied with a stain in the skull device. 
     
     
       7. An apparatus for producing colored glasses, comprising:
 a melting vessel for producing a melt from refuse glass or a glass batch; 
 skull device positioned downstream of the melt vessel; and 
 stain supply device; 
 the stain supply device connected in downstream of the melt vessel and upstream of the skull device. 
 
     
     
       8. An apparatus as claimed in  claim 7 , characterized in that from the melt vessel there are at least two downstream strands each connected with a respective skull device and a respective stain supply device. 
     
     
       9. An apparatus as claimed in  claim 7  wherein the skull device is a skull crucible. 
     
     
       10. An apparatus as claimed in  claim 7 , wherein the skull device is a skull groove. 
     
     
       11. An apparatus for producing colored glasses, comprising:
 a melt vessel for producing a melt from refuse glass or a glass batch; 
 a skull device positioned downstream of the melt vessel; 
 a stain supply device; 
 the stain supply device being assigned to the skull device in such a way that the stain is supplied directly to the melt contained in the skull device. 
 
     
     
       12. An apparatus as claimed in  claim 11 , characterized in that from the melt vessel there are at least two downstream strands each connected with a skull device and a stain supply device. 
     
     
       13. A method for producing colored glasses, comprising: first producing in a melting-in station a melt of a glass batch or refuse glass;
 processing the glass melt in at least one further vessel; 
 supplying the melt to a skull device in the course of further processing; and 
 supplying the melt with a stain after the melting-in station and before or in the skull device; 
 the melt and stain being subjected to convection currents in the skull device to cause mixing and homogenization of the melt and stain.
